When they encounter the roughened por- Fig. 3 a partial section taken substantially on tion of the ledge y Will be caused o bounce line 3-3 of Fig. 2. thereon, as indicated by the dotted lines in Fig. 1.

The embodiment of the invention illustrated in This bouncin 0f the 001118 On the roughened 30 the drawing comprises a suitable casing, preferface of the ledge l5 tends to Separate and e ably made of sheet metal as indicated, and havy Coins 0f different Sizes adhering to Ve ing its upper front portion constituted by a lying each other because obviously coins of differdownwardly and forwardly inclined glass front t Sizes, metals and Weights Will 100M168 d fie plate H, as indicated. ently on said roughened surface. As the coins 35 A coin entry slot is is provided centrally in p e d w the coin chute, they are p j cted the top of the casing it immediately behind the against the b elbOW 0f the ledge from glass plate ill and a suitable coin chute or hopwhich they bounce back into the lower reach of per 93, indicated by dotted lines in Fig. 1, may the coin chute, said bouncing again tending to 40 be provided for facilitating the insertion of coins eparate and free adhering ns frOm each other 40 through the slot l2 in edgewise relation. A guide so that by the time the coins pass into the lower plate i l, preferably of sheet metal, is arranged reach of the coin chute they will be separated in the casing it immediately behind and parallel from each other and pro in S ngle file. As to the glass front plate ll so as to form a space the coins rolling down the lower reach of the to receive the coins deposited through the slot chute it come to the respective slots l8, I9, 20, 45

i2. Immediately under the slot 12, the guide plate 2! and 22, they will tilt and fall through the first ii is provided with a guide ledge l5, as shown, slot they come to which is of sufiicient height to arranged in an inclined position and the lower pe mit. Thus all the dimes will fall through the portion of which is transversely grooved or waved slot 83, all of the pennies through the slot I9,

so as to roughen the same, as shown. The ledge all of the nickels through the slot 20, all of the 50 i5 terminates in an elbow portion, as shown, quarters through the slot 2| and all of the half which cooperates with a corresponding elbow dollars through the slot 22, thereby efficiently ledge 68 to form a coin chute down which the sorting said coins through the mere action of deposited coins will pass edgewise, as will be readgravity thereon.

ily understood. The lower reach of the ledge 16 Arranged in the casing l0 immediately below 55 the slots [8, I9, 20, 2| and 22 are corresponding coin drawers 24, 25, 26, 21 and 28 to receive the coins escaping through said slots. Each of the drawers operates, as indicated, through a suitable opening provided in the casing I0 and in a suitable registering compartment 30 preferably made of sheet metal, as indicated, and provided at its top with upwardly extending wings 3| positioned as shown to receive the coins from the corresponding slot and direct them into the corresponding coin drawer, as will be readily understood.

By this arrangement a simple and efficient coin sorter is provided which operates solely through the force of gravity, which is highly efficient in use and which can be economically produced. The specific form and arrangement of parts set forth is a simple and effective one for the purpose.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We therefore do not wish to be limited to the precise details disclosed but desire to avail ourselves of such modifications and variations as fall within the scope of the appended. claim.

We claim:

In a device for conveying coins to a coin sorter having means for separating face engaged coins, said means comprising an inclined guide having transverse ribs on the bottom thereof, whereby rolling coins will be repeatedly bounced to separate said coins.
